CAR-TRUCK SIDE FRAME.

Specification of Letters Patent. Pat nta Sept, 15, 1914..

Application filed May 2, 1914. Serial No. 836,043.

Side Frames; and I do hereby declare the following to be a full, clear, and exact dc scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to" an improvement in car truck s 'le frame, andis an improvement on the construction disclosed in application Serial Number 7 95,800 filed by me ()ctober 15th, 1913.

With the construction disclosed in the application above referred to, the journal boxes are specially made with wide flanges to en gage the bolt head and'washer WlllCh hold the journal box within the truck side frame.

The object of this invention is to provide means which operate only in an emergency to prevent the separation of the journal box from the truck side frame, and which are designed for use with the ordinary makes of journal boxes of the pedestal type, and

my invention consists in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in elevation of one end of a side frame'showing the journal box in place, and Fig. 2 is a view in section on the. line A43, of Fig. 1. l '1 represents the truck side frame having edestal jaws 2 and 3 for the axle or journal x 4:,which may be of any standard make. Journal boxes used on some car trucks, are provided with side flanges 5 which engage the pedestal jaws, for holding the boxes in place within the truck frame, and to adapt my im rovement to these boxesl make the inner jaw 2 oi the pedestal longer than the jaw 3, when necessary so that the means for holding the box in place may be located be low. the lowerends of said side flanges. It will of course be understood that both jaws 2 and 3 of the pedestal maybe of the same length, but in the present instance I have shown the inner jaws 2 longer than the outer jaws, the additional length being primarily for the attachment 'of the journal box holding means in a plane below the lower ends of the side flanges of the box.

The pedestal jaws 2 are each provided screwed onto the end of the bolt.

on their opposite faces, in a plane below the side flanges of the boxes, with the recessed seats 6 and with a bolt hole passing through the pedestal and communicating with both recesses.

Passing through thehole in the jaw, is the bolt 7, provided at one end with an enlarged rectangular head 8 the inner portion of'which rests within a recessed seat 6, and at its other end with a washer 9 also resting in a recess and held in place by a nut 10 The washer 9 corresponds in size and shape to the head 8 of the bolt, and both of them are made sufficiently long to project under the flange 5 at one side of the box and loplcthe latter against accidental displacement. With this construction the head of the bolt 1 and the washer are seated in recesses, and are held therein by the bolt, so that the bolt is not subjected to any stress other than that put, upon it by screwing up of the nut, the

head of the bolt, or the washer, or both taklog all stresses that may-be imposed'by contact with the flanges of the box and transmiting them to the frame. The bolt and its head and washer are simply means for preventing separation of the parts only in an emergency, as for instance, in the derail ment of a car, and are so located with relation to the box as not to interfere with the limited lateral motion of the box with relation to the side frame, or a limited lateral movement of the side frame with relation to the boxes. It is not essential that. both the head of the bolt and the washer should engage the flanges of the box, as the engagement of either the head of the bolt, or the washer with one flange of the box would be suflicient. t

By the construction of frame, boxes of any standard make can be used without any change, and when in place will be free,

to have all the movements necessary or desirable but will be held against possibility of accidental displacement.

Having fully described my invention what I claim as new and'desire to secure by Let ters-Patent, is

1. The combination of a truck side frame having pedestal jaws, one of which is provided on its side face with an open recessed seat accessible when the journal box is in.

place and a member fitting in said recessed seat andheld in place by a bolt, said mem- (MM .r

her being in a position to engage a flange of a journal box in the event of derailment 2. The combination of a truck side frame having pedestal jaws one of which is pro- 5 vWided with a recessed seat on each side face,

than the other, the longer jaw being provided with a recessed seat in itsside face adjacent the lower end of the jaw, and a member fitting in said'seat and held in place by a bolt, the said member being in a position to engage a flange of a journal box in the event of accidental'derailment.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
